Hello,
I don't find a list of the issues which are addressed by the development 
of the newer Ruby-Versions. Is such a list available somewhere?

I have the following problems:
(1) I currently need a Ruby-Script to be called back from another 
process, something like RPC. Is anything (working) out there except XML-
RPC? I want to avoid polling.

(2) Is the garbage collector under improvement? For meeting some "real-
time" requirements, I would like to have GC interruptable. This is 
related to (1). I had the idea to move GC into an own (real) thread.

(3) Is there work in progress to implement preemptive multitasking?

I think, number (3) is the real issue which would resolve most of (1) 
and (2).
